The electronic structure of the interface reveals that the WS2-GeC is a typical type-II heterostructure with the photoinduced electrons/holes transfer to the conduction/valence band of WS2 from the conduction/valence band of GeC, respectively. All the above suggest that the WS2-GeC composite has ...

monolayer lateral heterojunctions by a one-stepchemical vapor depositionmethod [23]. The well-controlled chemical composition from WS2to WSe2gave rise to a tunable band structure of the shell while keeping it constant of the core, and thus a tunable band alignment of theheterojunction. As shown ...
Among them, molybdenum disulphide (MoS2) and tungsten disulphide (WS2) are some of the best candidates due to their favorable band gap values and band edge alignments. Here, various perturbative corrections to the DFT electronic structure, e.g. GW, spin-orbit coupling, as well as many-body ...
Vertically stacked van der Waals heterostructures made of two-dimensional compounds are almost an infinite playground for the fabrication of nano-engineered materials for the most diverse applications. Unfortunately, high-throughput electronic structure
同时, 由于导带底和价带顶分别由WS2(或WSe2) 和GaN贡献, 这两种复合结构形成了第二类异质结. springer In the case of electrons in semiconductors, internal chemical potential is often specified relative to some convenient point in the band structure, e.g., to the bottom of the conduction band....
Here we report two-step direct epitaxial growth of the inorganic molecular-atomic Sb2O3/WS2 vdWHs. The thickness of Sb2O3 nanosheets on WS2 nanosheets can be tuned by variable growth temperatures. Oriented growth behavior of Sb2O3 on WS2 was determined through statistics. Optical images, ...
Herein, WS2 QDs, one of the emerging extraordinary zero-dimensional (0D) TMD materials, were applied to the preparation of novel 0D/2D heterojunctions of the WS2 QDs/BiOCl nanosheets. The obtained WS2/BiOCl composites exhibited ... PeiyuanXiao,JufengLou,HuixianZhang,... - 《Catalysis Science ...
The well-controlled chemical composition from WS2 to WSe2 gave rise to a tunable band structure of the shell while keeping it constant of the core, and thus a tunable band alignment of the heterojunction. As shown in Fig. 2a, the PL peak corresponding to WS2(1–x)Se2x shifts towards ...
